Linear Phase FIR Filters

February 8, 2019 by 3200 Creative

A significant benefit of FIR filters is that they can be guaranteed to have linear phase and not to introduce phase distortion. In this lesson you will learn the constraints place on the filter coefficients and frequency response when we require linear phase. For example, you will learn why certain orders cannot be used to obtain linear phase high pass filters. Understanding the relationship between filter coefficients and response is key to designing effective linear phase FIR filters.
